Design, operation and maintenance of Safety Instrumented Systems (SIS) just got easier

exSILentia Version 3 adds capabilities that will help users achieve a new level of consistency and pro- ductivity in the design of their Safety Instrumented Systems (SIS). This release enhances the existing suite of tools, including the industry leading tool for Safety Integrity Level (SIL) verification (SILver®). All-new functionality allows users to follow the entire IEC 61511 / ISA 84 functional safety lifecycle for the first time using a single tool. It also supports compliance with regulations such as OSHA PSM 1919.119 (USA) and Seveso II (Europe).
